Photoelectric sphygmomanometer of volume oscillometric method-type

摘要

The photoelectric sphygmomanometer is provided with electronic regulating devices (11, 12, 13) for setting the quantity of light, carrier-wave gain and pulsation gain on the basis of the level of the carrier wave immediately after the start of cuff depressurization. This makes it possible perform re-­regulation after the start of depressurization and eliminate an inability to take a measurement due to a fluctuation in the level of light received.
